Field of the Invention The present invention relates to a suspension wire or a self-supporting cable (SSD) laid between utility poles, and a spiral suspension is wound around the utility pole to be installed between the utility poles. When a cable is newly installed between utility poles so as to be supported, a leader of a cable drawstring used for moving the cable along the suspension line or the self-supporting cable (or spiral cable suspension). It is about ingredients. That is, by pulling the cable drawstring from one electric pole to the position of the other electric pole, the cable connected to the terminal side of the cable drawstring is supported and guided by the spiral cable suspending device and moved. As a result, the cable is installed between utility poles, but the present invention is directed to a cable drawstring leading tool used to move the tip of the cable drawstring from one utility pole side to another utility pole position. It is about.

A means for erection of a spiral suspender on the suspension, and for suspending the cable on the suspender and suspending the cable between utility poles is adopted. To arrange the cable along the suspension line or the self-supporting cable, A cable drawstring for pulling the cable must pass through the spiral sling. In the past, the only means for penetrating it was to hang it on a support line or to use a work platform for aerial work. The tip of the drawstring is moved from one electric pole to the other electric pole side.

（特願平１０−３６６１５１号）。For this reason, the inventors of the present invention do not need to arrange a worker between the electric poles, and the workability is excellent. A cable drawstring is connected to the rear end through a pressing wire made of a flexible material having a length corresponding to the distance between the electric poles, a main body long in the front-rear direction is formed with a concave shape on the opposite surface. And a pair of hooking pieces for hooking the hanging wire or the self-supporting cable with the hanging wire or the self-supporting cable interposed therebetween. The leading tool for the upright cable drawstring was first proposed (Japanese Patent Application No. 10-366151).

た。The above-mentioned structure proposed by the present inventors is excellent in workability as intended by the present inventors, but it is a pair standing upright with respect to the main piece. Since the locking piece of is fixed, it is not possible to selectively hook the hanging wire with a different outer diameter and the self-supporting cable and use it, and even if it can be done, the locking work is complicated. Next to
It has been found that there is a disadvantage that it is necessary to prepare a leading tool corresponding to each of the suspension wire and the self-supporting cable.
